Prima XL is the evolution of greatly appreciated BIXXIS steel Prima bicycle frame.

A more robust head tube and the soft shapes of the Eva fork make for a majestic bike but take nothing away in terms of its lightness, speed and responsiveness.

The Prima XL is available in five colors, with a Chris King Headset and a Titanium Seatpost made for BIXXIS by PMP in the specific 29,4mm diameter that BIXXIS decided being the best for his bikes.

The frame is made of Columbus Spirit Tubes Custom shaped on the specs that Doriano considered the best for the project.
